16 Claims.

This invention relates to smoking pipes in general.

I-Ieretoi'ore pipes being constructed with one channel or passage for drawing the smoke from the bowl to the mouth of user, alsoin other pipes wherein two channels or passages are prosmoke is being independently supplied in one channel or passage, and saliva, juice and particles of tobacco by gravity entering the other or second channel or passage. Thus, the fragrance of the tobacco as well as the efiiciency ofthe pipe will not be minimized. 1

Another object of this invention is to facilitate means with said two channels arrangement whereby the air force drawn through the smoke channel or passage is reduced before striking the mouth of user of the pipes and, thereby eliminate or reduce the usual biting of the tobacco smoke upon the tongue of user.

Another object of this invention is to make a new and novel filter and absorbent element adapted to engage said channels or passages and provided with wall portions forming means em-' bodied in this invention whereby nicotine, saliva and particles of tobacco are being eliminated in the travel path of the smoke sothat said smoke is greatly purified before reaching the mouth of user of pipe.

Another object of this invention is to make, in conjunction with said channels and said filter and absorbent element, a chamber at the junction of the bowl and the stem of the pipe which is conveniently and easily accessible for cleaning, and prepare the pipe for use.

Another and still essential object of this invention is to make, in conjunction with said channels, said filter and absorbent element and said chamber, new andnovel means which will facilitate cross ventilation for the area at the lower inner juncture of the bowl and the stem of pipes, thereby retaining dry condition of said area sufficiently to prevent the usual saturation of tobacco juice, saliva and also the mixing of tobacco dust therewith usually found thereat,

all of which prevents proper'draft through the struct pipes with an inclined joint at the intersection of the bowl and the stem and with said joint make means embodied in this invention which: let, Wlll facilitate cooling around the outlet portion of the bowl and thereby reduce the temperature of the heated air while it is being drawn through the smoke channel; 2nd, will afford easy and cheap construction of said two, channels and also said chamber; 3rd, will eliminate waste usually encountered with bowls having a portion of the stem of the pipe; 4th, afford efficient cleaning of the inside of pipes; 5th, eliminate destruction frequently encountered with the present joint between the portion of stem on the bowl and extension of the stem,

called mouth piece.

A, further object of this invention is to make, in conjunction with said joint, locking means of simple construction which, expansion and contraction thereat, will not damage by long use so as to produce loose connection between bowl and stem of pipes, as is experienced With threaded joint connections or other joint connections havmg metal part or parts such as pivot, hinges or the like. 7

A further object of this invention is to make new and novel latch means whereby bowl and stem of pipes are secured positively firm and rigid together and yet afford little effort in detaching the said bowl from its stem when the pipe requires cleaning.

Covers to prevent damage, which may be caused by sparks or burning tobacco from lighted pipes, do not meet the appeal of present day pipe smokers: one obvious reason for that is that these covers, although mounted in various man- 11ers, are always together with the bowl of pipes. Such an arrangement is objectionable, in that covers retard filling bowls inserted in pouches, and when filling bowls with tobacco is done by pouring, waste in the tobacco occurs especially during windy moments. And it is therefore a still further object of this invention to make means embodied in this invention which affords the covers to be positioned away from the bowl sufiiciently for inserting of the bowl unobstructively in a pouch for filling.

A further object of this invention is to make a pipe of the character described which is adaptable to any size and design, is economical and practical in use, and capable to give satisfaction in respect to sanitation and health.

Some of the objects of the invention having been stated, other objects and advantages, such as one stem can be made to fit or serve many bowls of difierent designs, will appear as the description proceeds when taken in connection with the accompanying drawing, in which- Fig. 1 is a side elevational view of a pipe constructed according to the invention.

Referring to one form of my invention illustrated in Figs. 1 to 14, inclusive, the pipe comprises the bowl member I, the stem member 2 which may be provided with a suitable tip porenter from the bottom of the bowl member and.

flow continuously around the bowl at 8 (see Figs. 5 and 6) to reduce substantially the heat, generated in the tobacco chamber la of the bowl member.

To attach the bowl member to the stem memher, the upper end of locking element 6 enters locking element 1 fromthe bottom of the stem member and the bowl member slidably is being arcuately moved upward to a predetermined position on the stem member, as is clearly illustrated. And, to prevent accidental downward sliding on the bowl member, in this instance, I prefer to form a slot 9 on the bowl member, adapted to engage a suitable latch Ill, which is pivotally mounted at l I upon the stem member 2.

This latch in is constructed so as to yieldingly wedge upward the bowl member, and at Illa tends to tighten the upper portion of joint 5 and the lower portion 5a also between the bowl member and stem member, and thereby complete a connection which produces stability and rigidity longitudinally and transversely in respect to the device.

In the bowl member is disposed a plurality of smoke apertures l2 preferably in vertical alignment, and a cavity 13 of suitable size. This cavity l3 serves as an extension of a chamber M, formed in the end of stem member 2, which is to house a filter and absorbent element l5, referred to hereinafter.

From this chamber l4 extend two channels l6 and IT in vertical alignment, and they intersect, preferably, each other at 18 which is adjacent the tip portion 3. The channel I6 extends further to said tip portion to serve as the smoke supply channel; and channel ll, being of larger size, adapted to serve as a draining channel traps at l8 saliva coming from the tip portion 3 and also tobacco juice introduced in channel Hi from th burning tobacco in the chamber la.

From the drawing, it is evident that the lower half of the filter and absorbent element I5 is for purpose of absorbing, and the other or upper half adapted for filtering the smoke before entering the channel I6. This element I5 is constructed so that its lower half closes the open mouth of channel I! in a manner to prevent leakage of air therethrough from chamber :4, and also from channel I! to channel l6 when the pipe is being used. And suction usually energized through the smoke channel I6 will not disrupt sediment in the drain channel ll of which diameter is of larger size than that of the smoke channel l6. Thus, the opening l8 connecting the smoke channel 15 and drain channel I! will produce interference with the heated flow of air in the smoke channel substantially to reduce its force before reaching the mouth of the smoker.

This lower half is provided with an extension l9 loosely engaging channel IT. This extension I9 is provided with a reduced portion Illa substantially fork shaped and which is of suitable length and reinforced with wire l5w. Obviously the branches of the fork facilitate an increased area of which surfaces quick absorption is attained and, the spaces therebetween form also open spaces upon which particles introduced in said drain channel, may be more readily adhered. This extension 19 is further provided with a cup or cavity l9b, referred to hereinafter. The upper half of element I 5 is provided with a suitable screen portion 26 integral therewith and disposed in alignment with smoke channel 16, and it is preferably substantially larger than the said channel, and also its inlet which is increased as at Ilia (see Fig. 5). And it is further evident that element I5 is constructed at its front with raised borders l5a, adapted to contact with the face of locking element 6 and serving a dual purpose: 1st, as a cushion for the bowl member in addition to sealing the joint thereat; and 2nd, is of suitable area and depth to form a vertical duct 21 .wherein the smoke gathers before entering the longitudinal channel l6, and thereby facilitates gradual purification of the smoke on the screen instead of straight or unbroken from the apertures l2, although said apertures l2 and said smoke channel It are in direct alignment. The absorbent element l may be mounted upon a suitable wire frame w, extended from.the lower portion toward the upper portions of the absorbent element, if so desired. distinctly understood that all matters pertaining to said absorbent element 15, described inthe specification and illustrated in the drawing, shall be considered as matters for another patent application, and which I intend to file. in the usual manner, prescribed.

22 is an aperture disposed transversely in the stem 2 with branches 23 and 24 extending downward from adjacent each of its open ends to connect in a manner so as to form, preferably, one open end or mouth 25, which is above and near the said cup or cavity, I919. Obviously, outer air will circulate continuously through the apertures 22, 23 and 24 and thus producing cross ventilation for the absorbent element i5 sufiiciently to prevent soakage of the lower inner It should be 5 area of the pipe with tobacco juice and saliva and thereby eliminate positively the bad or unpleasant odor common with pipes heretofore constructed. c

It is of course understood that I can provide an extension rearwardly of saidscreen to project in said smoke channel for absorbing tobacco juice which may beintroduce'd in said smoke channel in addition to filtering the smoke. And also, that instead of one open end at 25 a separate opening for the branches 23 and 24 can be made for airing the absorbent and filter element into the aperture 22.

It is obvious that when the pipe is used the screen 20 will assure a clean, and unobstructed smoke channel It; and the opening or inlet formed at It will intercept a portion of the heated air stream, existing in the smoke channel, sufficiently to cause to reduce its force before it strikes the mouth of user; and thereby reduces or eliminates biting on the tongue, without minimizing the quantity of the smoke, or producing hard drawing on the pipe.

The lid or cover 4 is of the ordinary type used on bowls. However it is provided with a left and a right brace or support 26 and 21 embodied in this invention but which I intend to make a matter for a separate patent application, and they are of suitable length and design.

These braces or supports are pivotally mounted at their free end on a suitable point upon the stem member 2 so that, the lid or cover member 4 can swingingly be thrown to a position shown in Fig. 8; whereby the bowl member becomes free of any of the many obstructions heretofore existing on bowls, especially so when suchbowls are filled from open tobacco pouches. Said pivoted ends may also be disposed at the open ends of said aperture 22 as shown in Fig. 11; but, wherein screws or nails would suffice in said first instance, stub axles 28 having a bore for ventilating said aperture 22 are provided. It is of course understood that I can provide a pivot for connecting the lid or cover member 4 to said braces or supports 26; but prefer said members 4, 26 and 21 to be one piece, which when normal tends to brace or support the bowl member.

It will be noted that the form shown and described is constructed with locking means so disposed whereby, when assembling and detaching the device, movement arcuately is preferred, and more specially, that saidmovement shall be substantially on the vertical axis of the device. However, it should be understood, that I can make said construction to facilitate assembling and detaching the device on movement substantially on a horizontal axis, and said movement may not necessarily be arcuately in respect to said horizontal axis of the device.

It is believed, that the foregoing conveys a clear understanding of the objects prefaced above. I

It will thus be seen that there is herein. described an article in which the several features of this invention are embodied, and which article in its actions attains the various objects of the invention and is well suited to meet the requirements of practical use.

It is obvious that the invention may be embodied in many forms and construction within the scope of the claims and I wish it to be un derstood that the form set forth in the drawing and specification is but the preferred one of many forms. Various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.
